    thanks

    A package is just a way of organizing your code. You organize the code in directories. For example if you have a package called "package database.util" you should put the Java code in a directory called "database/util/".

  • How can I use UC4 instead of SSIS Master Package deployed using project deployment model?

    Hi Folks,
    My team is planning to opt UC4 for scheduling the SQL Jobs and I have to come up with a plan to integrate it. 
    As of now, I do not have software licence in place to do some research. 
    If you have worked on it, can you tell me that how can I schedule SSIS packages using UC4. 
    Also, we are using SSIS project parameters (Project deployment Model). What kind of changes I have to make in SSIS packages to support UC4. Is it possible to pass parameters to SSIS package through UC4? If not, is there any alternativ?
    Appreciate your help!

  • How can I use a 3rd party XML parser such as xerces with OC4J ?

    Hi all tech experts,
    I am using Oracle Application Server 10g Release 2 (10.1.2) and i have
    installed Portal and Wireless and OracleAS Infrastructure on the same
    computer.
    i tried all the solutions on this thread
    Use of Xerces Parser in out application with Oracle App Server 9.0.4
    but still fighting.
    I have also posted this query on OTN on following thread
    How can I use a 3rd party XML parser such as xerces with OC4J?
    but no reply....
    Please help me on this issue.
    Since OC4J is preconfigured to use the Oracle XML parser which is xmlparserv2.jar.
    i have read the following article which states that
    OC4J is preconfigured to use the Oracle XML parser. The Oracle XML parser is fully JAXP 1.1 compatible and will serve the needs of applications which require JAXP functionality. This approach does not require the download, installation, and configuration of additional XML parsers.
    The Oracle XML parser (xmlparserv2.jar) is configured to load as a system level library of OC4J through it's inclusion as an entry in the Class-Path entry of the oc4j.jar Manifest.mf file. This results in the Oracle XML parser being used for all common deployment and packaging situations. You are not permitted to modify the Manifest.mf file of oc4j.jar.
    It must be noted that configuring OC4J to run with any additional XML parser or JDBC library is not a supported configuration. We do know customers who have managed to successfully replace the system level XML parser and the Oracle JDBC drivers that ship with the product, but we do not support this type of configuration due to the possibility of unexpected system behavior and system errors that might occur from replacing the tested and certified libraries.
    If you absolutely must use an additional XML parser such as xerces, then you have to start OC4J such that the xerces.jar file is loaded at a level above the OC4J system classpath. This can be accomplished using the -Xbootclasspath flag of the JRE.
    i have also run the following command
    java -Xbootclasspath/a:d:\xerces\xerces.jar -jar oc4j.jar
    but no success.
    How could i utilize my jar's like xerces.jar and xalan.jar for parsing instead of OC4J in-built parser ?
    All reply will be highly appreciated.
    Thnx in advance to all.

    Hi Neeraj Sidhaye,
    I am trying to deploy a sample xform application to the Oracle Application Server (10.1.3). However, I encountered the class loader issue that is similar to your stuation. I tried all the three solutions but the application is still use the Oracle xml paser class. I am wondering if you have any insight about this?
    Thanks for your help.

  • Can any one suggest me how can I use relative path inside SSIS pacakge to access config file ?

    Can any one suggest me how can I use relative path inside SSIS pacakge to access config file ? Please help me as its urgent.THanks for your help in advance.

    Hi Jay,
    SSIS can only recognize the absolute path of a XML Configuration file, the relative path is not supported. Furthermore, if the XML Configuration file is already generated, we can use the Environment variable package configuration type instead so that
    SSIS runtime automatically looks for the configuration file from the path defined in the environment variable. This is convenient when we need to deploy a package to different environment. We only need to define the environment variable for package configurations
    once on each server, and then the variable can be used by all the packages on this server.

  • How can I use bluetooth on my Satellite C850-B906

    Please help me. How can I use bluetooth on my C850-B906 Satellite. I can't find it on the search bottom and even in PC Device, bluetooth is not there. This laptop has bluetooth according to its specs. (Bluetooth / W-LAN (802.11B/G/N).
    Any good answer will be highly appreciated.
    Thanks in advance!

    Hi
    First of all: you are right: the Satellite C850-B906 supports Bluetooth
    http://www.toshibamea.com/CSPDF/Satellite_C850-B906-52424.pdf?ran=4qmi69d8z1
    But the notebook was not preinstalled with an Windows system and therefore I guess you installed the Windows OS (which one?) at you own hand.
    Probably you did not install the essential software / drivers which would allow you to use the BT
    The Realtek WLan module supports BT and therefore you have to install the Bluetooth Filter Driver Package a well as the BT stack from Toshiba driver page.
    After that you have to use the function key combination to enable the BT.

  • How Can I use a Variable  in Data Controls query. Frank Kindly check...

    Hii,
    I am using JDeveloper 11g ADF BC.
    My Requirement is that I hv a login screen which is taken from [http://blogs.oracle.com/shay/simpleJSFDBlogin.zip].
    I hv attached BC in this application. I want to use the login usercode in the next pages after login screen. Next screen contains 3 list items which will be populating based on the user. So I created <af:selectOneChoice> using the BC( Just drag & dropped the column into the page from the data controls). But in the data control i want to use this usercode for passing the condition. Now Data is coming without any condition.
    So How can I use the usercode in the Data controls query.
    When I tried to display the usercode in the next page it is showing by binding the value. its code is follows
    <af:outputText value="#{backing_getUser.uid}"

    Hi,
    I didn't look at the example, but if you want to secure your application then you should use container managed security. Read this .
    Anyway, you could add this before return "good"; in your login_action()
    FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("username", user);Then, you can access this from anywhere in the application by using #{sessionScope.username}.

  • How can I use PowerPivot tables like Excel tables -- printing, etc.?

    I can't seem to find any information on this anywhere, and even more surprisingly, no one else seems to have even asked this question...
    How can I use tables I create in the Excel PowerPivot window in the same ways I use tables that are in ordinary Excel worksheets, to accomplish tasks such as printing? I am able to use the powerful capabilities of PowerPivot to produce tables with precisely
    the information I need for reports -- connecting data from multiple tables/sources, filtering, etc. -- but then there doesn't seem to be any way to actually print what I'm seeing, nor can I seem to access cells in these PowerPivot tables from Excel worksheets.
    If a PowerPivot table is conceptually an Excel table with additional power in terms of pulling in data and relating it, it would seem appropriate that all the power of Excel could be brought to bear on these PowerPivot tables, but on the contrary, the available
    operations are limited. if, instead, a PowerPivot table is more correctly viewed as a data source that Excel worksheets can connect to, that would be fine, and indeed, one
    can use a PowerPivot table as a data source -- except it can't be brought into an Excel worksheet as an ordinary Excel table, unlike most other data sources.
    I hope I'm missing something really obvious, and that someone can point out what it is. Thanks.

    Kirchh,
    When PowerPivot was first designed, the decision was to integrate closely to Sharepoint to allow for team sharing. We are constantly evaluating customer feedback to add more features, and this has been one of the feedbacks we have received. We will consider
    supporting this in the future but with no gurantee.

    -- This posting is provided "AS IS" with no warranties, and confers no rights
    I'm not questioning why PowerPivot is closely integrated with SharePoint. I'm asking why connecting to the PowerPivot model from within Excel was intentionally blocked by Microsoft, when all the functionality to do so appears to be present.
    Is creating an OLE DB connection in Excel to PowerPivot as $Embedded$ supported?
    No support. It was originally designed for SharePoint. This changed with Power Pivot for Excel 2013 (it's packaged with it). Originally the scope (in 2010 through 2012) was that it was for SharePoint users. So it became more obvious through that to market it
    toward all Excel users. Thus the recent changes.

    }OK, My questions are:
    [1]. what I generated XML by XSTream is very complicated, especially for object LocationTest, Can we make it as simple as others such as Person object??
    [2]. after I run it, LocationTest will popup and a red ball in a panel will dsiplay, after I change red ball's position, I hope to persist it to xml, then when I read it back, I hope to get same picture, ie, red ball stiil in old position, How to do that??
    Thanks a lot!!

    Positive feedback? Then please take this in a positive way: if you want to work on persisting Java objects into XML, then GUI programming is irrelevant to that goal. The 1,000 lines of code you posted there appeared to me to have a whole lot of GUI code in it. You should produce a smaller (much smaller) example of what you want to do. Calling the working code from your GUI program should come later.

  • No ISA slot available in PC. How can I use PCI-85 Modbus Plus card with Lookout?

    My application is to communicate with two Modicon PLCs using Modicon's ModBus Plus (PCI based PCI-85) network card inside my PC, and using Lookout as an SCADA software. Since there is no ISA slot available in new PCs, I can not use Modicon's ISA-85 Modbus Plus networc card. But Lookout does not support PCI based PCI-85 card, how can I use PCI-85 card then, with Lookout? Why doesn't Lookout support it? I asked the following question from from the Modicon's representative about it:
    If I purchase Modbus Plus Driver Suite CD (SWMXDS001, 05, or 10 etc),will I be able to use Lookout SCADA software (by the way, it supports standard MB+ prtocol) for my application? If yes, can I use any version of an
    y of the ISA, PCI, or PCMCIA based MB+ card?
    His answer was:
    The Modbus Plus Driver Suite will talk to any version of card, PCMCIA, ISA, and PCI. The question now is will the SCADA package you are
    planning on using be able to talk to the Modbus Plus Driver Suite? You must contact National Instruments and ask them if they support Modbus Plus, and if
    they used the MB+ system developement kit to develop their product. Or if they wrote their own MB+ drivers, do they work with Modicon hardware?

    Hi,
    currently Lookout does not support the PCI-85 card. The only card supported for Modbus Plus is SA-85. Please see for further information:
    Where can I Find Drivers for Communicating to PLCs, RTUs, and Other Industrial Hardware?
    How to configure the SA-85 card for Modbus Plus
    Hope this helps
